299
In non-recursive mode, all the named items are added, regardless
300
of whether they were previously ignored. A warning is given if
301
any of the named files are already versioned.
302
303
In recursive mode (the default), files are treated the same way
304
but the behaviour for directories is different. Directories that
305
are already versioned do not give a warning. All directories,
306
whether already versioned or not, are searched for files or
307
subdirectories that are neither versioned or ignored, and these
308
are added. This search proceeds recursively into versioned
309
directories. If no names are given '.' is assumed.
310
311
Therefore simply saying 'bzr add' will version all files that
312
are currently unknown.
313
314
Adding a file whose parent directory is not versioned will
315
implicitly add the parent, and so on up to the root. This means
316
you should never need to explicitly add a directory, they'll just
317
get added when you add a file in the directory.

319
--dry-run will show which files would be added, but not actually
320
add them.
321
322
--file-ids-from will try to use the file ids from the supplied path.
323
It looks up ids trying to find a matching parent directory with the
324
same filename, and then by pure path. This option is rarely needed
325
but can be useful when adding the same logical file into two
326
branches that will be merged later (without showing the two different
327
adds as a conflict). It is also useful when merging another project

into a subdirectory of this one.

If arguments are given, they are regular expressions that say which tests
2547
should run. Tests matching any expression are run, and other tests are
2548
not run.
2549
2550
Alternatively if --first is given, matching tests are run first and then
2551
all other tests are run. This is useful if you have been working in a
2552
particular area, but want to make sure nothing else was broken.
2553
2554
If --exclude is given, tests that match that regular expression are
2555
excluded, regardless of whether they match --first or not.
2556
2557
To help catch accidential dependencies between tests, the --randomize
2558
option is useful. In most cases, the argument used is the word 'now'.
2559
Note that the seed used for the random number generator is displayed
2560
when this option is used. The seed can be explicitly passed as the
2561
argument to this option if required. This enables reproduction of the
2562
actual ordering used if and when an order sensitive problem is encountered.
2563
2564
If --list-only is given, the tests that would be run are listed. This is
2565
useful when combined with --first, --exclude and/or --randomize to
2566
understand their impact. The test harness reports "Listed nn tests in ..."
2567
instead of "Ran nn tests in ..." when list mode is enabled.
2568
2569
If the global option '--no-plugins' is given, plugins are not loaded
2570
before running the selftests. This has two effects: features provided or
2571
modified by plugins will not be tested, and tests provided by plugins will
2572
not be run.
2573
2574
Tests that need working space on disk use a common temporary directory,
2575
typically inside $TMPDIR or /tmp.
2576
2577
:Examples:
2578
Run only tests relating to 'ignore'::

The source of the merge can be specified either in the form of a branch,
2769
or in the form of a path to a file containing a merge directive generated
2770
with bzr send. If neither is specified, the default is the upstream branch
2771
or the branch most recently merged using --remember.
2772
2773
When merging a branch, by default the tip will be merged. To pick a different
2774
revision, pass --revision. If you specify two values, the first will be used as
2775
BASE and the second one as OTHER. Merging individual revisions, or a subset of
2776
available revisions, like this is commonly referred to as "cherrypicking".
2777
2778
Revision numbers are always relative to the branch being merged.
2779
2780
By default, bzr will try to merge in all new work from the other
2781
branch, automatically determining an appropriate base. If this
2782
fails, you may need to give an explicit base.
2783
2784
Merge will do its best to combine the changes in two branches, but there
2785
are some kinds of problems only a human can fix. When it encounters those,
2786
it will mark a conflict. A conflict means that you need to fix something,
2787
before you should commit.
2788
2789
Use bzr resolve when you have fixed a problem. See also bzr conflicts.
2790
2791
If there is no default branch set, the first merge will set it. After
2792
that, you can omit the branch to use the default. To change the
2793
default, use --remember. The value will only be saved if the remote
2794
location can be accessed.
2795
2796
The results of the merge are placed into the destination working
2797
directory, where they can be reviewed (with bzr diff), tested, and then
2798
committed to record the result of the merge.
2799
2800
merge refuses to run if there are any uncommitted changes, unless

--force is given.

Giving a list of files will revert only those files. Otherwise, all files
3160
will be reverted. If the revision is not specified with '--revision', the
3161
last committed revision is used.
3162
3163
To remove only some changes, without reverting to a prior version, use
3164
merge instead. For example, "merge . --revision -2..-3" will remove the
3165
changes introduced by -2, without affecting the changes introduced by -1.
3166
Or to remove certain changes on a hunk-by-hunk basis, see the Shelf plugin.
3167
3168
By default, any files that have been manually changed will be backed up
3169
first. (Files changed only by merge are not backed up.) Backup files have
3170
'.~#~' appended to their name, where # is a number.
3171
3172
When you provide files, you can use their current pathname or the pathname
3173
from the target revision. So you can use revert to "undelete" a file by
3174
name. If you name a directory, all the contents of that directory will be
3175
reverted.
3176
3177
Any files that have been newly added since that revision will be deleted,

3180
3181
The working tree contains a list of pending merged revisions, which will
3182
be included as parents in the next commit. Normally, revert clears that
3183
list as well as reverting the files. If any files are specified, revert
3184
leaves the pending merge list alone and reverts only the files. Use "bzr
3185
revert ." in the tree root to revert all files but keep the merge record,

"""Mail or create a merge-directive for submiting changes.
4052
4053
A merge directive provides many things needed for requesting merges:
4054
4055
* A machine-readable description of the merge to perform
4056
4057
* An optional patch that is a preview of the changes requested
4058
4059
* An optional bundle of revision data, so that the changes can be applied
4060
directly from the merge directive, without retrieving data from a
4061
branch.
4062
4063
If --no-bundle is specified, then public_branch is needed (and must be
4064
up-to-date), so that the receiver can perform the merge using the
4065
public_branch. The public_branch is always included if known, so that
4066
people can check it later.
4067
4068
The submit branch defaults to the parent, but can be overridden. Both
4069
submit branch and public branch will be remembered if supplied.
4070
4071
If a public_branch is known for the submit_branch, that public submit
4072
branch is used in the merge instructions. This means that a local mirror
4073
can be used as your actual submit branch, once you have set public_branch
4074
for that mirror.
4075
4076
Mail is sent using your preferred mail program. This should be transparent
4077
on Windows (it uses MAPI). On Linux, it requires the xdg-email utility.
4078
If the preferred client can't be found (or used), your editor will be used.
4079
4080
To use a specific mail program, set the mail_client configuration option.
4081
(For Thunderbird 1.5, this works around some bugs.) Supported values for
4082
specific clients are "evolution", "kmail", "mutt", and "thunderbird";
4083
generic options are "default", "editor", "mapi", and "xdg-email".
4084
4085
If mail is being sent, a to address is required. This can be supplied
4086
either on the commandline, by setting the submit_to configuration
4087
option in the branch itself or the child_submit_to configuration option
4088
in the submit branch.
4089
4090
Two formats are currently supported: "4" uses revision bundle format 4 and
4091
merge directive format 2. It is significantly faster and smaller than
4092
older formats. It is compatible with Bazaar 0.19 and later. It is the
4093
default. "0.9" uses revision bundle format 0.9 and merge directive
4094
format 1. It is compatible with Bazaar 0.12 - 0.18.
4095
4096
Merge directives are applied using the merge command or the pull command.

For lightweight checkouts, this changes the branch being referenced.

For heavyweight checkouts, this checks that there are no local commits

versus the current bound branch, then it makes the local branch a mirror
4485
of the new location and binds to it.
4486
4487
In both cases, the working tree is updated and uncommitted changes

are merged. The user can commit or revert these as they desire.

Pending merges need to be committed or reverted before using switch.
